DATAMAN S4 MANUAL
Byte-Wide RAMS may also be emulated. If the
EMULead is to be plugged
into the socket meant for a STATIC RAM, the
PROM configuration must
be set to a PROM which has similar address and
data pin-out. The
write-line must not be connected through the
EMULead, but must go
directly to the Flying Write Lead. One way to do
this might be to
cut the Write-pin off a spare EMULead, used only
for this purpose.
Another way is to use an intermediate socket
plugged into the EMULead,
which has the write-pin removed.
Power Usage when Emulating.
The time-out termination is disabled while
emulating, but the low-battery
termination still works. Emulation places an extra
current-drain
on the battery: the actual current depending on the
load driven by
the data-pins and the amount of time the internal
memory is enabled. 100
milliamps is typical which is about 6hrs on a full
charge. If the
charger is plugged-in then there is no time-limit.
The ESCape key
will terminate the emulate mode.
